CASTING- MECI-IANISM FOB TYPOGRAPHICAL MACHINES.

T all whom it may concern:

Be it known that l, THOMAS \V. dorms, a citizen of the United States, residing at Brooklyn, in the county (if-Kings and-State of New York, haveinvented new and useful Improvements in Casting Mechanism for .Typographical Machines, of which the following is a mpecification;

line casting machines ;and more especially to those of the linotype class where n an assembled line of matrices is presented to a mold and the slug is cast in the mold, the slug being formed with a charactei' bearmg edge which conforms to the characters borne by the matrices.

lhe primary object of the ixfventionLis to provide a novel and improved mold, cooperating 'li'lOllfillPlQCE for the metal pot, and

' ejectorfwhereby slugs of different lengths 'may produced with facility, requiring minimum labor and time in the adjustment 'of the machine. Another object is to provide novel and improved trimming means for the slug which is capable, without adjustment or change, of trimming the slugs of different lengths cast in the mold.

Specification, Letters Patent.

This invention'relates to improvements in Fig. 7 represents, on an enlarged scale, a section taken through the mold and the mouthpiece of themetal pot, the latter bein r shown in engagement with the mold, and

*ig. 8 represents a transverse section through the mold showing the mouthpiece and a part of the spout of the metal pot in section.

Fig. 9 represents an elevation of a portion of the mouthpiece of the metal pot as viewed fron'i the front, and

Fig. 10 represents a section on the, line 1()10 of Fig. 9.

Similar parts are designated by the same reference characters in the several views.

The present invention is applicable generally to line casting machines of different types capable of casting slugs having different characters along an edge thereof. The invention is particularly applicable to machines of the linotype class, it being so shown in the present instance. It is to be understood, however, that theinvention is not restricted to the precise construction shown as equivalent constructions are con-' Patented May 18, 1920.

templated and will be included within the scope of the claims.

In the present instance, 1 represents the so-called mold disk or wheel which is commonly used in machines of the linotype class,

this mold disk serving to support one or moreniolds and being operative to set such mold or molds in position for casting and also in position for ejection of the cast slug therefrom. The improved mold provided by the present invention comprises a mold body 2 which is fixed to the face of the of the part of the mold cavity to receive the type metah Preferably, and as shown, an auxiliary liner or equivalent part 7 is used,

this auxiliary liper having plain 'orflat ends .to fit between t], e mold cape: and the liners Sand 6. and theiauxiliary liner being formed with ribs 8 which, when the auxiliary liner is in position, project into the The elements of the mold are gather by any suitable means,

mold cavity.

spaced longitudinally of the mold at regal lar intervals with regard to the graduated measures of the length of a line. It is most advantageous to space the ribs8 at intervals of two ems, the length ofline being usually measured in ems. It will be understood that ordinarily a number of auxiliary liners will be provided, each of these auxiliary liners having a different number of ribs, but the ribs on the'difii'erent liners are similarly located in a direction longitudinally of the mold when the different liners are applied thereto. By referring to Fig. a it will be observed that the left-hand portion of the mold cavitydcsignated generally as 10 is intersected by the ribs 8, the right-hand'end 10 of the mold cavity being unobstructed by these ribs. The length of the slug cast in the rigl1t-l1and portion .10 of the mold cavity will, in consequence, correspond to the distance between the inner edge of the right-hand liner 6 and the adjacent rib S on the auxiliary liner. By using an auxiliury liner having one less rib, that is to say,

' right-hand portion thereof, the'lcugth of the with the right-hand rib 8 omitted, the length of the portion 10 of the mold cavity and,

in consequence, the length of the slug cast in the mold willbe increased two ems. By using other auxiliary liners having greater numbers of the ribs 8 omitted from the slug can be increased to different line measures varying by intervals of two cms. Likewise, by using auxiliary liners having greater numbers of ribs on the right-hand portion thereof, the length of the portion 10" of the mold cavity and, in consequence. the length of the slug cast therein may be reduced to measures varying by two ems. In this way, a slug having any desired length within the capacity of the machine measured in even numbers of produced using a standard right-hand liner 6. Slugs measured in odd numbers of ems may be produced in conjunction with the auxiliary ribbed liners by substituting a shorter end liner 6", this end liner 6 being one em shorter than the standard cud liner 6. Likewise. liucs varying in half cm 'longths can be (ibtained by the use of the different auxiliary ribbed liners by using a right-hand end liner (9" of intermediate lengththis end liner (5" being half an em shorter than the standard end liner 6 and half an em longer than the shortestend liner 6.

According to the present invention, the intrmluction of an auxiliary liner having ems may be:

p the line of matrices,

"the character faces at line of produce a slug of the desired, length will automatically determine the length of the mold cavity utilized in the casting of the slug. 'This result is-accomplished by the 'aid of av mouthpiece 11 for the metal pot which mouthpiece is provided with'the' usual .metal-injectingorifices 12 for introducing the metal into'the right-hand portion 10 of the mold cavity, these orifices 12 being usually spaced at distances of one em cam, and an additional orifice 13 is provided be yond the right-hand end of the orifices 12? to. introduce type metal into the portion, 10 of the mold cavity which is extended when the shortest end "liner 6 is used. Toward thelc'ft-hand end of the mouthpiece 11 the latter is provided With pairs of orifices 14, each pair of theseorifices 14; being spaced apart at distances of two ems. Each pair of the orifices 14 is so located in the mouthpiece of themetal pot that when the latter comes into engagement with the rear face of the mold, each rib 8 of the auxiliary liner will be opposite to a corresponding pair of these orifices 14 and will close them, the auxiliary liners for the casting of the slugs of longer lengths and which have one or more of the ribs 8 omitted therefrom causing corresponding numbers of these pairs of orifices 14 to be uncovered. The orifices 14 which are coveredby the ribs 8 of the auxiliary liner are closed thereby, and

. hence no metal from the metal pot can enter j the portions of the mold cavity occupied by such ribs. Metal, however, Will be per-- mitted to-enter the mold cavity throughthe usual orifices 12 and through such pairs of the orifices 14: as are uncovered by the omitted rib or ribs 8 of the auxiliary liners and also through the additional single ori fice 13 when the shortest end liner 6 is used for the casting of slugs of'odd lengths. The pairs of orifices 14 in the mouthpiece are preferably located directly above one another and, as shown in Fig. .8, the upper orifice diverges laterally with respect to the lower orifice of the respective 'pairin order that the metal from the upper and lower ori fices of each pair will strike the character faces of the matricesat different points spaced one em along the lengthoi the line,

although the --airs of orifices are spaced two ems apart. in consequence, the metal will be evenly distributed along the length of while the two-em spacing of the orifices enables the tongues of the ejector blade to be made relatively Wide and strong. The mouthpiece 11 may be fitted in a suitable Way inthe spout 1.5 of the metal pot and the metal pot may be of the type usually employed in machines of the linotype class for forcing the molten type metal into the mold cavitv and asainst presented to the front face of the mold. By using auxiliary liners .having transverse ribs of different numbers arranged at gradu-- ated intervals longitudinally thereof in con-- junction with a mouthpiece having metalinjecting orifices correspondingly spaced,

' into those portions of the mold cavity-occupied by the ribs.

The present invention provides a novel and improved ejector for removing the slug from the mold, this same ejector serving to remove the slugs irrespective of-the lengths thereof. The ejector, as shown, comprises a blade 16 havin a tongue 17 of a' width corresponding, pre erably, to the slug of shortest length which it may be desired to cast in the mold, and a number of ton use 18, the tongue 17 ofthe ejector bla e being operative through the right-hand portion 10 of the mold cavity, and the tongues 18 being operative through the recesses which are :formed between the ribs 8 of the auxiliary liner. The: ejector blade 16 is attached to a slide 19 which may correspond to the ejector slide commonly used in machines of the linotype class, the ejector slide being reciprocated at appropriate intervals by a link 20 which is 'operatively connected to an arm 21, thfe latter being actuated or controlled by a suitable cam. .The ejector blade 16 is guided to reciprocate in ali'nement with'the mold cavity and the tongues the slug is cast anda jalso the recesses which are formed between the ribs 8 of the auxiliary liner irrespective of the length of the slug cast in the mold, and hencea single ejector blade is capable of ejecting t e shortest slugs, the longest slugs within the capacity of the mold, and slugs of all intermediate lengths. I I

The present invention also provides means for trimming the flat sides of the slugs cast in the mold irrespective of whether the end liner 6 or the end liner 6 is used. As shown, the trimming mechanism comprises a vertical channel or chute 23 which is preferably mounted on the usual column of the main frame of the machine to enable the vise frame to be swung open or closed without disturbing the trimming mechanism. This channel 23 occupies a position immedimely infront of the mold when the latter is brought to the slug-ejecting position and the ejector blade 16 preferably has a stroke just sufficient to carry it through the mold, pushing the slug from the mold in advance of the blade and into the channel 23. The

trimming means comprises a stationary trimming knife 24 which is arranged at one side of the chute 23 and a cutter 25 which is arranged at the opposite side of the' chute, the cutter 25 being shown in the form ofa revolving toothed cutteriand it is adapted to trim the upper side of the slug which usually has transverse ribs thereon correspond. ing to transverse grooves which are formed in the upper wall of'the mold cavity. The cutter 25 is carried by a lever 26, the latter being pivoted at 27 to a stationary part of the machine fram'e,and means is provided at the upper end of the lever 26 to set it in different positions-whereby the distance between the knife 24 and the cutter 25 may be varied to trim slugs to different thicknesses. As shown, a graduated eccentric or cam 28 is pivoted at 29 to a suitable stationary part ofthe machine frame, and the upper end of the lever 26 is held against the eccentric or cam surface of the .cam 28 by a spring 30. Rotation of the cam or eccentric 28 will set the cutter 25 at different distances from the knife or cutter 24 to conform to slugs of different thicknesses. In using a rotary toothed cutter, as shown the same maybe driven through gears 31,atlexible shaft 32, and a belt pulley 33', the latter being arranged in the present instance to. cooperate with a belt 34 which passes over pulleys 35 and 36. Each slug after ejection from the mold is held above the cutters 24 and 25' by a spring ,37 which may be attached to the lever 26. Feeding of the slug 10o endwise between the cutters 24 and 25' is effected by a vertically reciprocatory slide 38 having a projection 39 thereon which is 17 and 18 thereon will operate through the mold cavity, including the portion in which arrangedto engage the upper end of the slug, the slide 38 being operated by a rack 40 thereon which coiiperates' with a pinion 41, the pinion 41 being connected to a pinion 42 and the latter cooperating with a rack 43 on a forwardly and r'earwardly moving rack bar 44, this rack bar being conveniently connected at 45 to the arm 21 Which actuates the ejector slide. After trimming, the slug descends by gravity into a galley chute 46. In' Figs.- 1 and 2, the slugs are designated S, one slug occupying a position above the trimming cutters, and v another being shown below the cutters. In Fig. 1, a slug is shown in the galley chute.

y trimming the slugs by a trimming mech anism as described, it is .unnecessary to ad trimming mechanism being necessaryonly when the thickness of the slug is to' be changed, and such adjustment can be made easily and quickly cam or eccentric 28.

The present invention provides a mold by simply rotating the y and cooperative ejector and trimming mechanism which are particularly useful in. the

casting of type slugs for advertising or display matter, or in other connections Where numerous changes in the length or thickness of the slugs is required. The mold can be quickly and easily, changed to cast slugs of dii'lerent lengths by insebting auxiliary liners having the appropriate number of ribs thereon, "and the particular. auxiliary liner used will, in each instance, automati-- irrespective of the varying lengths of the slugs, and. hence changing of the ejector to conform to the length of the slug is unneo essary.

Preferably, and as shown, the rear edge of the auxiliary liner 7 is formed with an upturned. flange 7, and the rear edge of the mold cap l is correspondingly cut away, as shown in Fig. 8, thus enabling the mold cap to be removed without requiring removal of the mold body from the mold disk. Qbviously, the ribs 8 may be formed on the lower faces of the mold caps, in which case the use of auxiliary liners would be unnecessary, and, furthermore, both kin res or cutters of the trimming mechanism .may be composed of plain stationary blades like the blade 24.
